During the Christmas season, you typically hear a lot about porch pirates... but what about porch pitchers?

One West Knoxville family witnessed a delivery man throwing packages at their door—all on their doorbell security camera.

Chris Marr was at home Tuesday when he heard a thud at his door.

“Me being a disabled veteran, I jumped up at that point,” he said. “I thought something crazy had happened.”

So he checked his doorbell camera, only to find a worker had made the noises after they chucked packages in a hurry.

One package contained items for work, and the other was a present for his nephew. Thankfully, the packages weren’t damaged.

“It's just disrespectful to us,” Marr said.

Marr and his wife Jessica said they saw the same thing happen the day before. However, that incident wasn't caught on camera.

Marr heard a thud at the door—that package was a very special gift for Jessica: a Queen album signed by Freddie Mercury.

“So I was prepping to tell her I’m so sorry, but this has been messed up,” Marr said. “Luckily the person I’d gotten it from online had packaged it really, really well.”

It’s a busy time of year for deliveries. Delivery services like UPS say they expect to deliver around 800 million packages between Thanksgiving and New Year—up from about 760 million last year.

Lance Saunders, a University of Tennessee supply chain professor at the Haslam College of Business, says that means double the work.

“When you have that many workers trying to get packages out as fast as possible so it’s on your doorstep, unfortunately some of them try to get it done a little too fast,” Saunders said.

The Marr family says they hope this doesn’t happen to someone else this season.

“It’s just not right,” Marr said. “You should respect other people’s stuff.”

In a statement, UPS told 10News, “Thank you for bringing this to our attention. UPS employees receive regular training on the company’s methods and procedures to safely transport and deliver packages. We will investigate the situation and take appropriate action.”
